Abstract:The purpose of the research was to study the effect of different doses of winter rye grain extrudate on nitrogen metabolism in the body and growth intensity of replacement heifers at the age of 12–15 months of the Holsteinized black-and-white breed in the conditions of the dairy complex. Heifers of the control group received a diet, the concentrate part of which consisted of 50.0% (1.0 kg) of standard mixed fodder КR-3 (GOST 9268–2015), 50.0% (1.0 kg) – of rolled barley.
